"I am happy with my penis, I know nobody has the size I have. I would like to be in the Guinness Book of Records but they don’t recognise this record."

But despite his pride, members of the medical community have urged him to at least consider a penile reduction.

Doctor Jesus David Salazar Gonzalez said: “We have advised him 'Mr Roberto, the best thing for you is that the doctors give a normal shape to your penis so that it doesn’t hurt you, in order to have sexual relationships, in order to have children.'

"But he doesn’t accept it, he’d rather have a penis bigger than the rest of the people.

“In Latin culture whoever has the bigger penis is more macho.

"It’s something that makes him different to the rest of the people and makes him feels special."

Doctors have also been able to offer some insight in just how Roberto’s penis became quite so large - they say he has been stretching his penis with weights since his teens.

Dr Jesus David Salazar Gonzalez said: "He was obsessed with the penis length.

“He began with this enlargement since he was a teenager, wrapping some bands around his penis with some weights and trying to stretch it."

The sheer size of Roberto’s penis causes him a number of health problems, including frequent urinary tract infections because not all his urine escapes his lengthy foreskin, and he keeps his colossal member wrapped in bandages to escape chaffing.

He is also unable to sleep chest down and has to put his penis on its own pillow to escape discomfort during the night.

An active sex life is also off limits for Roberto as his penis has too much girth to have intercourse.
